T5: what's the use of onPassivate
Hi,
I tried the example under 'Render request only' in the following link, if I
remove the :
long onPassivate() { return _productId; }
still works, what's the use of it? thanks.

Hi Nick,
It is still not clear to me, example:
< a t:type="pagelink" page="member" context="rowBltn.id" > which generates:
< a href="/myapp/member/4" id="pagelink_11" />
and the onActivate already has access to the id(4 in this case) without the
need to use onPassivate,
public Class onActivate(Long id) {
return null;
}
I must miss something here.

It's a way of persisting the product id into the link context.
Client side persistence to avoid using the sesssion.
That would be important for links on the detail page.
Cheers,
Nick.
